(1), the use of the pump head is lower than the pump lift too much lead to excessive current flow after the over-current solution to control the outlet valve opening to flow control small and the current down to allow the current range, or change the diameter of the impeller Lower the pump head.
　　
(2), water pump motor damp lead to excessive current.
　　
(3), pump motor quality problems.
　　
(4), the pump voltage is unstable.
